Sotetsu 10000 series

Data (as of 22 Feb 2026)

History

Sotetsu has been developing its own trains with unique features, but the company had introduced rolling stock based on JR East's commuter train in the 2000s, to reduce costs. The 10000 series is based on JR East E231 series (commuter-train group). Three ten-carriage units and five eight-car units were introduced in total, and their bands were initially green and yellow, but they were changed to blue and orange by 2009.

In 2020, a ten-car unit was refurbished and repainted to YOKOHAMA NAVYBLUE livery. Other units have been gradually refurbished, but some of them are yet to be repainted, and thus they now look almost identical to 11000 series.

Current Operations & Future Prospects

The 10000 series are used on the entire Sotetsu network, but not often on the Shin-Yokohama Line and never for through-services. The refurbishment programme takes place until late-2020s.

Sotetsu has been refurbishing other 10000 series units since 2021 without repainting, making them extremely difficult to distinguish from 11000 series.

In 2024, the company restored its original livery to a unit...just partly.
